LOCK.

Specification of Letters Patent.

Patented Dec. 4, 1906.

I Application filed May 2 1906. Serial No. 314,830.

To all whom it may concern:

Be it known that I, PETER EBBEsoN, a citizen of the United States, and a resident of St..Paul, in thecounty of Howard and State of Nebraska, have invented a new and Improved Look, of which the following is a ful clear, and exact description.

This invention is an improvement in looks, embod g a novel manner of operation from one or th sides of a door, as desired.

The invention has for obj ects,among others, to provide a lock with a latching means WhlCh will securelyhold the door when closed to. the door-stop, thereby preventing any rattling or shaklng of the door, and also to provide a sim 1e and convenient means hatch and a means-for looking t e latch which cannot be picked or relpased by one not in possession of the proper ey. I

The lock which I have conceived to accomplish the above objects is of a neat and compact appearance and can be readily applie to a door or other closure at a comparatively small expense.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures. v

Figure 1 is a side elevation of the look as applied to a door, the door being broken away around the lock. Fig. 2 is a vertical section through the door-jamb and that part of the lock to clearly show the construction of the latching-disk, taken substantially on the line 2 2 in Fig. 1.- Fig. 3 is a'face view of the door jamb and stop with a plate for carrying the'latching-stud and roller applied thereto. Fig.- 4 is a transverse section through the lock on the line 4 4 of Figs. 1 and .5 showing the osition assumed by the parts when the latching-disk is locked. Fig. 5 is a longitudinal vertical central section on the line 5 5 of' Fig. 4. Fig. 6 is a longitudinal horizontal section through the locking-barrel on-the line 66 of Fig. 4. Fig. 7 is a view similar to Fig. 4 with the locking-tumbler pushed to one side by a key for withdrawing the locking-bolt. Fig. 8' is a view similar to Fig. 4'with a blank inserted in, the keyhole and pushing the tumbler to one side to show 4 20, projecting at each side 0 the position taken by the tumbler when it is attempted to unlock the latching-disk with other than a proper key, and Fig. 9 is an edge view of a door with a single latching-disk applied.

Referring to Figs. 1 to 8, inclusive, the numerals 1 and 2 indicate, respectively, a door-jamb and a stop to which is secured by screws 3 or other attaching means a plate 4,

let in flush with thedoor-jamb and projecting into the door-stop 2, where it is preferably provided with a flange 5, flush at its upper edge with the face of said stop. The plate 4 carries journaled on a headed screw or stud 6 a roller 7 at about the point shown in Fig. 3 for a pur ose hereinafter made ap parent. The bOt' y of the lock is made up of three disk-like sections 8, 9, and 10' of about the same width, the two disks 8 and 10 being rotatably fixed at opposite sides of the disk 9 and are almost substantially identical, varying only in their general formation in that the disk 8 is provided with an eccentric slot 11, entering the periphery at a suitable point for cooperating with the roller 7 in drawing the door tightly closed to the doorstep. The central disk 9 has flanges 12 and 13 at the bottom and top portions thereof, conforming to and extending over this portion of the periphery of the disk 8, the flanges being turned perpendicularly outwardly in a plane with the outer face of the disk 8 to form attaching means 14 and 15 for the disk 9, which is to be fixed in an opening cut in the edge of the door for containing the look,

as shown in Figs. 1 and 2. 4

The locking mechanism of the fixed disk 9 is best shown in Figs. 4, 5, and 6, consisting of a revoluble barrel 16, passing horizontally through the upper half of the disk and j'ournaled 1n bearin s at .17 at each side thereof Said barrel is held from longitudinal movement by a bead or flange 18 at each of-its ends. Mounted 'in the barrel at its center is a tumbler 19, having doublyconcavedoblong ends19 ivoted on a pin f the tumbler and passing into grooves21 and 22, respectively. The portion of the pivot-pin in the groove 21 is pressed on each side by a spring 23 to normally hold the tumbler in the center of the barrel. The bottom and top edges of the tumbler slide in vertical guide-slots 24 in the barrel, and the top edge of thetumbler carries a projection 25 for cooperating with areshaped projections 26, extending downwardly from a head 27, secured to and passing into the disk. The projections 26 are three in number, equally spaced apart to permit sufficient space between them for the projection 25 to pass therebetween, and are also arranged concentric with the tumbler in a chamber 28 at one side of the head 27, providing passages 29 and 30 at their ends substantially at ri ht angles to each other. The barrel 16 has xed to it directly below the tumbler 19 a bolt 31, entering when the disks 8 and 10 are looked a diametrical groove 32 in the top face of a beveled pinion 33, said pinion being journaled in a plvot-bolt 34 by means of a headed pin 35 passing through it. The pivot-bolt 34 is designed to hold the disks face to face against separation and passes through beveled pinions 36 and 37, 1.e spectively, fixed to the disks 8 and 10 and meshing with the beveled pinion 33.

When the lock has been fixed to the door, as shown in Fig. 1, and the door closed, with the eccentric slot 11 engaged with the roller 7, knobs 38, carried by arms 39, projecting from each of the rotatable disks 8 and 10, will occupy the lowest position of their'limited movement, as shown in Fig. 2. In this position the engagement of the roller and slot will firmly press the edge of the dooragainst the stop, thereby preventing any looseness or rattle of the latter.

If desired to lock the door while the latching-disk and roller are engaged, a key 40, as shown in Fig. 7, with a reduced end 40 of an exact counterpart of the end faces 19 of the tumbler 19 and shoulders 41, adapted to contact with the projecting edges of the guideslots 24, is inserted and pressed on until the projection 25 registers with an opening between the projections 26, which will occur when the lower-or upper end of the tumbler contacts with an end of'one of the guide-slots 24. The barrel 16 and the'mechanism carried thereby are then rotated by the key projectin the bolt 31 into the groove 32, thereby loc ing the gearing and the disks forming a part thereof to the disk 9. Bynow withdrawing the key 40 the spring '23 pressing on the pivot-pin'20 returns the tumbler to the center of the barrel, with the projection 25 in the path of the central projection 26,which, of course, now prevents any turning of the barrel, as is evident.

' Should any one attempt to pick the lock, as b inserting a blank 42 into the keyhole, as s own in Fig. 8, the peculiar concaved formation of the end faces 19 of the tumbler 19 will cause the tumbler 19 to turn on its pivot 20 and revent the register of the projection 25 wit a space between the proeled pinion in jections 26. The unlocking of the disk is performed by reversing the operation just described and the door opened by raising either of the knobs 38. As shown, the locking and unlocking operation may be carried on at either side of the door, since the tumbler'is capable of being moved from its normal central position to register with the opening at each side of the central projection 26.

In Fig. 9 is shown an embodiment of my invention in its simplest form, consisting of a single rotatable disk 43, adapted to be engaged with rollers 43 and identical in construction to the latching-disk 8 and carrying a knob 44 and an arm 45, corresponding to the knob 38 and arm 39. This form of my invention is preferred in use .on safes, iceboxes, v&c., in which structures it is only necessary to operate the latching-disk from one side of the door.

The precise embodiment of my invention is not material, provided its essential characteristics are employed, as pointed out in the annexed claims.

Having thus described my invention, l: claim as new and desire to secure by Letters Patent 1.
